The Advantages of LED Grow Lights Over HPS Grow LightsTraditionally growers have opted to use high pressure sodium (HPS) lights due to their bountiful harvests. They have been tested thoroughly and proven to work. They work in both the hydroponics industry and the agricultural grow market. However, they are very energy intensive.LED grow lights on the other hand are a relatively new technology. They have only began to become popular within the last couple of years. Currently many growers doubt that they can produce the same yields as HPS. Many companies have spent the last several researching and developing LED cultivation lighting and we believe they are at the stage to compete with HPS. LEDs have several inherent advantages over HPS.The first advantage of LED is their energy usage. In a typical grow operation energy is one of the main expenses. An 1000W HPS can cost up to $60 a month to operate. LED cultivation lights on the other hand only cost around $20 a month in electrical costs for the same yield. This means that in a typical year you will save close to $500 by switching to LED. Also, it means less complicated electrical wiring since you do not have to deal with as high of current draws.Another advantage of LED over HPS is their expected life time. HPS light bulbs typically last 6 months before they need to be replaced. LED bulbs on the other hand are expected to last up to 5 years before needing to be replaced. Besides the reduced maintenance costs for large grow operations, it also means that your bulbs will keep producing a constant level of light and not diminish with time.For those doubting LED's ability to deliver quality yields there has been numerous tests done showing that they can indeed deliver massive yields. In our research we have found that they can deliver the same yield as HPS will using two thirds less electricity.Another advantage of LED grow lights over HPS is their heat usage. HPS require specialized cooling systems. LED on the other hand do not and produce only one sixth the heat of HPS.The reason LED grow lights can work so well is they target the exact wavelengths of light needed for plant growth.If you are thinking of trying out LED grow lights now is the perfect time. Many companies offer a free return policy on their lights so you can try them out worry free....
